The actor offered the note of inspiration concerning the late Paul Walker at a charity event attended by the latter's brother and father.
He disclosed this while attending a charity event on Saturday, September 17, 2016, which also had in attendance Walker's father and brother, Us Magazine reports.
"Paul was very instrumental in my segue into fatherhood. He was the one that told me to go to the hospital. He's the one that told me to cut the umbilical cord."
"He told me to cut the umbilical cord! [He was] the only person, in California, that knew I was about to have a child."
"He must've been God-sent because he put me on the right path. He set me up. And when we did the first Fast & Furious, I was already 30 years old or something, but he was a father."
"When we were in the cars in between takes, he would tell me, 'Hey, Vin, it's not a scary thing to become a father' [and] give me all the good advice."
"Next thing I know, I am a dad ... [He] is why I named my daughter Pauline because of the credit that Paul Walker deserves in my personal life."
Diesel already has two daughters, Hania and Pauline, and a son named Vincent.
The late Paul Walker was not just an actor to his "Fast & Furious" team, who often engage in a feeling of nostalgia about the times they spent together before his passing.
